Hi Doris i brought 1 in flower last yr 2 & that 2 hasnt flowered ? :/

Wait a little as mine hasn't flowered yet but there are signs that it will flower. If your plant is healthy then I think you shouldn't worry too much.

Some plants need to settle in for a year or two before putting on a show. Try feeding it with Tomato food to encourage flowering.

The commonest reason for hydrangeas not flowering seems to be pruning at the wrong time. Hydrangeas need to have last year's dead flower heads taken off in April, cutting back to a good pair of buds. Any dead growth can also be removed at the same time - cutting this off low down. If the centre of the bush is becoming overcrowded you can take out a few of the oldest stems then too. Don't prune at any other time - leave the old flowers on over winter to help protect the buds from frost.

I agree they may sulk if moved - I moved two hydrangeas two years ago - one flowered last year, they both have a few flowers coming this year, but they're not really "settled" yet.
